Gyms are currently closed in Scotland due to the ongoing pandemic, but the 21-year-old has been sharing his workout tips on BoundFitness' Instagram page.

Chatto and Kuda Tapatapa, the founder of BoundFitness, also recently posted a live 50-minute HIIT workout video.

It wasn't just Chatto's technique that viewers were focusing on.

"It looks like hard work…maybe take your top off," one commenter wrote, according to MailOnline.

"So muscular…so sexy," another added.

Chatto, who is 26th in line to the British throne, specializes in "strength and endurance training with a military focus," according to his bio on BoundFitness' Instagram page.

"I was lucky enough to row around the UK this summer!" he added in the caption. "This gave me a lot of experience in training myself and the team to complete the challenging expedition. I've found physical training to be an essential cornerstone in improving my own mental health and I want to share this with others."
